Step-by-Step Guide

01

Install Server Stack

SSH into your fresh Ubuntu 22.04/24.04 server and run the command below. Installs NGINX with FlashXPRESS FastCGI Cache, MariaDB 11.4, PHP 8.4 (fallback 8.3/8.2/8.1), Redis, WP-CLI, Certbot, UFW, Fail2Ban, and fx CLI.

bash
bash <(curl -sSL https://wp.flashxpress.cloud/install.sh)
02

Create WordPress + Cache

Creates a fully configured WordPress site. Downloads WordPress, creates MariaDB database, configures NGINX with FastCGI Cache, sets up Redis Object Cache, and creates optimized server block.

bash
fx site create example.com
03

Install Free SSL

Secures your site with Let's Encrypt SSL. Generates HTTPS config with HSTS headers, HTTP-to-HTTPS redirect, preserves all cache settings. Auto-renews via cron.

bash
fx ssl install example.com

Verify FastCGI Cache

After all 3 steps, verify caching is working.

Run this command:

bash
curl -I https://yourdomain.com

You should see:

X-Cache: FlashXpress HIT

First: FlashXpress MISS or FlashXpress BYPASS. Refresh → FlashXpress HIT

Troubleshooting

Common questions and solutions.

Check your server meets requirements (Ubuntu 22.04/24.04, 1GB+ RAM, root access). Ensure no other web server is running. Run fx status to check services.
FlashXpress is designed for fresh servers. Existing web services (Apache, MySQL) may cause conflicts. Use a clean server.
Run fx update. It preserves your site configurations and data.
Yes! PHP 8.4 default with fallback to 8.3/8.2/8.1. Switch with fx php switch 8.3.
Run curl -I https://yourdomain.com. First visit shows FlashXpress MISS, subsequent shows FlashXpress HIT.
Auto-renews via Certbot cron. Manual: fx ssl renew yourdomain.com.
